Arothron spp. (Citrinellus) are a group of small pufferfish admired for their distinctive shape and engaging behaviour. Due to their genus-level identification, care should be conservative and tailored to typical Arothron species requirements.
Temperament and Compatibility: These puffers are generally semi-aggressive and can be territorial, especially towards other puffers or slow-moving fish. They are best kept singly or in a large enough tank to provide ample territory. Compatibility with other robust species is possible, but caution is advised with smaller or delicate tankmates.
Diet: Carnivorous by nature, Arothron spp. require a varied diet including meaty foods such as molluscs, crustaceans, and specialised frozen or prepared puffer diets. Their strong beaks need regular wear, so offering hard-shelled prey items is beneficial.
Tank Requirements: A minimum tank size of 120 litres (approximately 30 gallons) is recommended for small Arothron spp. to provide sufficient swimming space and territory. The aquarium should be well-established with stable water parameters, moderate water flow, and plenty of hiding places created by live rock or décor.
Reef Compatibility: With caution. These puffers may nip at invertebrates and corals, so they are generally not considered reef safe in sensitive reef systems.
Water Parameters: Maintain temperature between 24-27°C, salinity at 1.020-1.025 SG, pH 8.1-8.4, and stable water quality with regular maintenance.
Overall, Arothron spp. (Citrinellus) are fascinating additions for marine aquarists prepared to meet their specific care needs and provide a suitable environment.
